We have a few helper functions like the following: ``` std::error_code create*Dumper(...) ``` In fact we do not need or want to use `std::error_code` and the code can be simpler if we just return `std::unique_ptr<ObjDumper>`. This patch does this change and refines the signature of `createDumper` as well. Differential revision: https://reviews.llvm.org/D86718
